Improvement in oil-cans



UNITED STATES PATENT EEICE.

FERDINAND LEER, OF NEW YORK, N. Y.

IMPROVEMENT IN OIL-CANS.

Specification forming part of Letters Patent No. 158,721, dated January12,1875; application filed December 9, 1874.

'To all whom it may concern:

Be it known that I, FERDINAND LEER, of the city, county, and State ofNew York, have invented a certain new and useful Improvement in Oilers,of which the following is a specification z This invention isillustrated in the accompanying drawing, in which Figure 1 represents avertical central section. similar view of a modification thereof.

Similar letters indicate corresponding parts.

This invention consists in a valve, the stem of which rests upon thespring-bottom of the oiler, and which serves to close an opening orvent-hole leading from the air-space of the oiler into an open drip-pipesurrounding the discharge-pipe, in such a manner that when the oiler isnot in use thebvent-hole is open and the air in the oiler can expandfreely, but

-as soon as the spring-bottom of the oiler is pressed inward the valvecloses the vent-hole, and then the oil is forced out through thedischarge-pipe.

The invention further consists in combining, with an oiler having anelastic bottom or wall, a drip-pipe, a valve, an adjusting-screw, anddischarge-pipe, in such a manner that the position of the valve can becontrolled for regulating the quantity of oil to be ejected through thedischarge-pipe.

The invention finally consists of a wire or rod constructed with anenlarged or looped end of a length about equal to the length of thedischarge-pipe; said wire or rod being arranged Within such pipeprincipally for the purpose of reducing the size of thedischargepassage; said wire or rod and discharge-pipe being combinedwith an oiler having an elastic bottom or wall in such a manner that acomparatively small compression of the air within the oiler will befound sufficient to eject the required quantity of oil out through thedischarge.

In the drawing, the letter A designates an oiler, which is constructedwith an elastic bottom, a. B is the discharge-pipe, which extendsthrough the drip-pipe C, so that any oil which may run down on theoutside of the discharge-pipefis carried back into the chamber b, whichcommunicates by a hole, c, with Fig. 2 is athe interior of the oiler.Beneath this hole is situated a valve, d, the stem of which is depressedby a spring, e, so that the lower end of said stem bears upon the bottomof the oiler, while the valve leaves the hole c open. When the bottom ofthe oiler is forced inward the valve closes the hole, and by thecompression of the air in the oiler the oil is forced out through thedischarge-pipe. The position of the valve-l can -be adjusted -by meansof a screw, f, which extends up into the chamber b, and which can bereached Whenever the supply-opening ofthe oiler is opened. Through thedischarge-pipe B extends a wire, g, the outer end of which is bentbackward, so as to form a loop, 71,. By means of this loop any drop ofoil which may adhere to the mouth of the discharge-pipe when the oileris placed in an upright position is sucked back into the discharge-pipe,and the outside of the oiler is always clean. Said wire also serves toclean out the discharge-pipe, and it reduces the passage through saidpipe to such an extent that a comparatively small compression of the airin the oiler is sufficient to force the required quantity of oil outthrough the discharge-pipe. The inner end of the discharge-pipe may becurved downward, as shown in Fig. l, so that its inner opening issubmerged beneath the oil in the oiler; or the inner end of said pipemay be extended beneath the top of the oiler, as shown in Fig. 2, sothat the oiler must be turned up in order to bring the inner opening ofthe dischargepipe below the level of the oil. In either case the oilcontained in the oiler can be forced out nearly to the last drop, and ifthe oiler is placed in an upright position no oil will be forced out bythe expansion ot' the air in the oiler.

What I claim as new, and desire to secure by Letters Patenti s 1. Thevalve d, provided with a stem, which bears on the elastic bottom of anoiler, A, in combination with the vent-hole c and dischargepipe B,constructed and operating substantiallyA as shown and described.

2. In combination with an oiler having an elastic bottom, a drip-pipe,G, and ventopening c, valve d, adjusting-screw f, and dischargepipe B,constructed to operate substantially as described.

3. A Wire or rod, g, constructed with an enlarged or looped end, and ofa length' about equal to the discharge-pipe, and arranged within suchpipe, for4 reducing the size of the discharge-passage, in combinationwith each other and with an oiler having an elastic Wall7 for ejectngoil through the discharge-pipe by compression of air Within the oiler,substantially as herein shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this8th day of December7 1874.
